Fig. 13 is an end view of some of the parts shown in Fi 12, certain other parts also being shown. ig. 14 is an enlarged side elevation partly in section showing the vibratory ribbon carrier and various devices employed for positioning the same. Figs. 15,16 and 17 are views corresponding to Fig. 14 but omitting some of the parts shown in said Fig. 14 and showing other arts in diiferent relations from those in wh ch they appear in said Fig. 14.

Referring first more especially to Figs. 1 and 2, the main frame of the machine is shown as comprising a base 1, corner posts 2 and a top plate '3. Key levers 4 are fulcrumed on a member 5 and are each connected by a link 6, a lever 7 and a second link 8 with a type bar 9 pivotally mounted in a hanger 10 secured to a stationary support 11, the latter being suitably fixed to the main frame of the machine. The type bars normally rest on a type rest 12 and each is provided with an upper case type and a lower case type which, when the t pe bars are actuated, may cooperate with t e front face of a platen 13 which is adapted to r0 tate in a carrier presently to be described, said carrier being shiftably mounted on a carriage comprising side bars 14 and front and rear bars numbered respectively 15 and 16. The front and rear bars are ,grooved to end crate with anti-friction balls 17, said bal s also cooperating with grooved front and rear guide rails numbered res ectively 18 and 19 which are fixed to the rame of the machine above the top plate. Arms 20 pivoted to'the carria e carry a feed rack 21 which normally mes es with a feed pinion 22 fixed to the front end of a shaft (not shown), said shaft bearing in a bracket 23 secured to the to plate. An escapement wheel 24 is operatlvely connected with said shaft and cooperates with escapement dogs 25 mounted at the top of a .dog carrier or rocker 26 {which is connected by a link 27 with acunved arm 28 suitably secured to a ckshaft 29.,fsaid rock lsliafi. ivoted a .itsendsfltolsarew piv -.30 sec on t Nearits ends the rock el -li is provided. with ncarwardlv ex ending [arms 31am wh an e links 32 carrying a universal bar 33 underlying the key levers. \Vhen one of the latter is actuated to operate its associate type bar, the universal bar will be operated to cause the carriage feeding or letter feeding devices above described to cooperate in a known manner to permit the carriage to be moved a letter space toward the left under the influence of a spring drum 34 with which the carriage is connected by a hand or strap 255.

The platen is provided with an axle 311i which is mounted in a carrier comprising end bars or plates 37 connected by a cross bar 38, only one of said end bars being shown. Each end bar is pivotally connected by links 39 with the side bars 1 1 of the carriage. A roller 40 mounted at the front of the bar 38 cooperates with a shiftable guide rail 41 which is supported near its ends on upright rods 42 movable through openings in the top plate, said rods 42 being fixed to and rising from a cross bar 43. Said cross bar, in turn, is carried by vertical rods 4-4 each pivotally connected at t5 with a shift lever -16 having a fixed pivot 47 intermediate its ends and tcrn'iinating at the front of the machine in a key button 48. During the travel of the carriage back and forth across the top plate the relation of the platen 13 and the platen carrier with said carriage will ordinarily remain unaltered, the roller 40 running back and forth over the shift rail 41. If, however, it be desired to print in upper case one of the shift keys 48 may be depressed, raising the shift frame, comprising the rods 14, bar 43, arms 12 and shift rail '11. and thereby raising the platen carrier and platen to upper case position. The parts thus far described are not original with me and are not claimed herein save in combination with other devices presently to be described.

A ribbon 49 is secured to and wound upon ribbon spools 50, said ribbon spools being vertically disposed bcncath the top plate, one at each side of the machine and forward of the platen, as shown in Figs. 1 and 9. Each ribbon spool is sccured to the forward end of a horizontal shaft 51 jonrnalcd in lugs 52 depending from the top plate. Said shaft is provided at its rear end with a beveled pinion 5;) which is adapted to cooperate with a beveled driving pinion 54 secured to a. driving or power shaft 55 journaled in lugs 56 depending from the top plate. The driving shaft is connected with and adapted to receive motion from the spring drum 34 by a train of devices comprising beveled pinions 57 and 58 which are constantly in mesh with each other. The pinion 58 is suitably connected with the spring drum when the latter turns to draw the carriage in printing direction, as by the usual pawl 34 and ratchet wheel (Fig. 1). The p on 57 is sliclablv coir nected with the driving shaft 55 so that the shaft may be moved endwisc to connect one or the other of the driving pinions 5t with its associate pinion 53, thereby,causiug the associate ribbon spool to be turned to wind the ribbon thereon. The shaft 53 may be conncctwl with the pinion 57 so as to bc turncd by the latter 1" any suitable means, su h as that illustrated in Fig. '2. said means as there shown comprising a pin 5T rigidly connected with the pinion 57 and cor'ipcra tire with an opening in a crank arm 55 fast on the shaft This mode of connecting the shaft with the driving pinion is not. novel and it is not deemed necessary to de scribe it in detail.

The ribbon 4-) is led upward from each ribbon spool through an opening in the top plate and ovc' a pair of guide members 59 suitably secured tbcrcto. Midway between the ribbon spools the ribbon is threaded through a vibratory ribbon carrier or vibrator, the construction of which shown clearly in. Figs. 3 and 4-. Said ribbon carrier or vibrator is composed of two nicnd'icrs adjustably secured together. The upper of said members comprises a. stem (it) bifurcated at its uppcr end portion to provide two arms til, the latter being bent to form loops (32 through which the ribbon is threaded. that portion of the ribbon between the loops (r2 bcing hereinafter referred to as the printing portion Jf the ribbon. The lower nicnibcr or part o l of the ribbon carrier is shown detached in Fig. 4 and is in the form of an oblong liat plate which may be cut out in places as shown to lighten it. A strap or friction plate it is secured by screws 35 to the upper end of the member 63 and the lower end portion of the stem (it) is oonl w' d between the strap and the n'icinbcr (13 in such a my that when the screws are tightcncd the two parts of the ribbon carrier are held in a fixed relation. The lower end of the member (33 is provided with tw rcarwardly extcnding tabs or cars (36 which are perforated to receive headed shouldered scrcws 67, the latter serving as pivots for the ribbon carric' and engaging in tapped openings tits formed in an extension (19 projecting forward from the lower end of a rack member or ribbon carrier support shown detached in Fig. (1. The ribbon carrier support further comprises rearwardly extending cars formed with perf rations 71 and upwardly extending arms 72 between which is arranged and suitably secured a rack 73. The arms 72 are provided with outwardly extending ribs or tongues 74 which are adapted to slidably engage in grooves 75 formed in the upright parallel arms 76 of a guide member which is most clearly shown in Fig. 5. The guide member is provided with a web 77 joining the lower end portions of the arms 76 forward of the grooves and further comprises rearwardly extending tabs or ears 78 each of which is divided by a vertical slot or kerf 79 into two parts. the slot 79 and the outer parts of the ears 78 being laterally outside of the arms To. The ears 78 are formed with perforations .90. The guide member is secured to the back of the cross bar 43 by screws 81, so that when the cross bar 43 is shifted during the platen shifting operation, the guide member will also be shifted. A combined slide rod and shaft 82 passes through the openings 90 and near the right-hand side of the machine bears in an opening 83 t'ornn-d in one arm 84 of a U-shaped bracket (Figs. 3 and i). which further comprises another and parallel arm and a portion 86 connerting the two arms. Said bracket is secured to the rear of the bar 43 by screws The slide rod 82 is adapted to be moved back and for h endwise and also to be given rotary movement as presently to be described. and a finger button 87 secured to its right-hand end is provided for manipulative purposes. A' flange or collar 88 is formed n or secured to the slide rod near the tingi button, providing a circumferential depression or groove 89 between said flange and said finger button 3'). A latch 90. clearly shown in Figs. 3 and 7, is pivoted on a shouldered screw 91 secured to the bracket arm 85. The latch is maintained pressed against the outer face of said bracket arm by a coiled spring 92 surrounding the screw 91 and said latch is provided with an open mouthed slot 93 which is adapted to coiiperate with the depression 89 or with the rod 8:? at the opposite side of the tlange S8 in order to maintain said rod in one or another of two longitudinal posi tions in either of which it may be given rotary movement.

The rod 82 carries devices which control the position of the ribbon carrier support and ribbon carrier whereby different width- \vise port ions of the ribbon may be utilized. In one of the longitudinal positions in which the rod may be set" the devices it carries operate to automatically and progressively vary the position of the ribbon carrier support and ribbon carrier so that the ribbon as it is fed longitudinally may also be fed crosswise and used progressively back and forth from one edge to the other; while in the other set position of the rod the automatic crosswise. feeding devices are thrown out of operation and the rod is adapted to he turned by hand to one or another of a plurality of predetermined positions. thereby setting the ribbon carrier in an unvarying normal position and providing for the utilization of the ribbon in one or another of a plurality of paths parallel with each other and extending lengthwise of the rib- 56 bun. This, of course, is especially useful in two-color work. In another of the positions in which the ribbon carrier. may be set by hand the ribbon is withdrawn entirely from cooperation with the types so that the latter may be employed for mimeograplnng or like purposes.

The connection between the rod 82 and the ribbon carrier support is made through a pinion 94, the teeth of which mesh with a rack 73 on the carrier support, said pinion being fast on a collar 95 which is fixed to the rod 82 by screws 97 (Fig. 8), said collar projecting beyond the opposite faces of the pinion 94 and being cut away at its ends to form shoulders which provide engaging faces numbered respectively 98 and 99. The engaging faces 98 are adapted to cooperate with corresponding faces 100 formed on a sleeve 101 which surrounds the rod 82 and bears in the openings in the left-hand ears or tabs 78 (Fig. 3). Arranged in the lefthand slot 79 and fast on the sleeve 101 is a crank arm 102 which is connected with the ribbon driving shaft by mechanism presently to be described. The engaging faces 99 are adapted to cooperate wlth corresponding faces 103 formed at the inner end of a sleeve 104 which surrounds the rod 82 and bears in the right-hand ears or tabs 78. Arranged in the right-hand slot 79 and fast on the sleeve 104 is a flange or collar 105 formed with notches 106, 107 and 108, said notches being adapted to cooperate with a spring detent 109 secured by a screw 110 to the. under side of the bar 43. It will be apparent that the spring detent and the notched collar 105 will, when the rod 82 is connected with said collar, cooperate to maintain the rod 82 in any one of three poand ribbon carrier in set positions normally.

The construction is such that when the rod 92 is pulled outward or to the right the engaging faces 98 and 100 will cooperate to lock the collar 95 and the sleeve 101 in a fixed relation, thereby also maintaining the sleeve 101 in a fixed relation with the rod 82. The crank arm 102 is fast on the sleeve 101 and consequently when the sleeve and the collar 95 are locked as shown in Fig. 3 any motion transmitted to the crank arm 102 from thcribbon driving shaft by mechanism presently to be described, will thence be transmitted to the pinion 9t and through it to the rack 73, the ribbon carrier support and the ribbon carrier itself. During the transmission of such motion it will be understood that the rod 82 operates as a shaft and that the sleeve 101 acts as a collar on said shaft. turning in the bearing openings in the rightrhand tabs 01' ears 78. It will t'fittt ltltfl rod and shaft $2 is hehl from lonfurther be understood that at this time the t l ,Ilt'ttllllill movement outwartl or towartl the 1 right by the sleere ltll \vhieh in turn hehl t'roni loneittnlinal movement by the erank arm l t. which is eontinetl between thettwo let'thantl ears TR.

The. use ot elliptical gears to vary the position of a vibratory ribbon carrier not original with me and is not claimed M 1' se by me.

The meehanism above described operates .to vary the position ofthe ribbon carrier support mat the ribbon arrier so that when the ribbon earrier is actuated. (litterent witlthwise portions of the ribbon Will be preentetl to the types. The means for aetie :lti1]; the ribbon earrier. which will now be described, is connected to said carrier through a log or extension 122 which is fast on :Illtt pt'tljtt'ts ruarwartlly from the lower part HZ) ot the earrier (Fig. ti].

The t-onstruetion is sueh that the 't'ulermn pin antl the arms 1;". are rigitllt serured to- ;y-ther. the l'nh-rnm pin serving to maintain s-ihl arms a tiXetl tlistaneo apart at their upper enlls :tlltl the hub portion i213 being; atlaptetl to turn freely on Hillti tul rum pin lwtwren saitl arms 1317. The lower enlls of the members or arms lil are formed with tappeil holes to rot-rive shouhleretl support.- in; serews 'litl whieh pass thrt'utgh the bean innopeninggs Tl on the ears TU ot' the ribbon earrier support. tlllll are atlaptetl to turn treelr therein. It will be llUtttl that. both the ribbon rarrier atul the arms ['39 are pivotetl at their lower ends on the ribbon earrier support and eonneetetl above by the lug 12L antl the lever arm 124. and hence are adaptltt to more substantially in parallelism when the ribbon carrier is vibrated vibratory movements are communicated to the ribbon carrier through the lever arm 125 which in turn receives its motion from a stud or pin 132 extending laterally from a lug 28 which is integral with the curved arm 28 and extends upwardly and rearwardly from its junction therewith. It will be understood that. when any meet the ke levers 4 is actuated, the rock shaft 29 will he turned and the stud 132'forced against the lever arm 125, moving the latter rearward. The upper or ribbon carrying end of the ribbon carrier is constantly urged forward away from the front face of the platen by a leaf spring 133 which is secured to the under side of the ribbon carrier support by a headed screw 134 and is curved beneath the pivotal axis of the ribbon carrier, contacting with the rear face of said carrier above said pivotal axis as shown in difierent views; for example, in Fig. 1.. As a consequence, the

ribbon carrier, when under the operative control of the key levers, is normally held away fromfthe front face of the platen by the spring 133 as shown for example in Fig. 1, the printing portion of the ribbon being opposite or horizontally on a line with the printing point but separated or removed therefrom. \Vhen a key lever is depressed and the pin 132 acts against the lever arm 125, the operating lever is forced bodily rearward, carrying with it the ribbon carrier until the ribbon is brought close to the print ng point on the platen. A pad 135 supported on an arm 136 which is secured by a headed screw 137 to the shift rail 41,

is adapted to cooperate with the rear face of the part 3 and servesas a limiting stop for the ribbon carrier in its movement toward the printing point. This movement of the ribbon carrier is a rotary one, said carrier turning on the pivot screws 67 while the arms 129 turn in their bearings 71, permitting the bodily rearward movement of the bell crank operating lever. During this bodily rearward movement of the bell crank lever there may also be a slight pivotal movement thereof on the bodily moving fulcrum pin 12S. At'this time the pivots of the ribbon carrier and of the members or arms 125) are relatively fixed, by which is meant that the are fixed during printing operations. By reason of what may be termed theparallel motion connection between the ribbon carrier and its operating lever, and the members 12!) the extent of vil'u'atory movement communicated to said ribbon carrier will always be substantially the same,.althongh, by reason of the up and down movement oi lbc ribbon carrier support lever nrm 125 will vary. will take place both when the carrier support is slidably adjusted on and relatively to gear 114 or driven gear and the partscarricd thcrcl [v.the point of engagement between the stud 132 and the Such variatum the guide member, and also when said sup-- port and said guide member are moved together at the times when the platen shift takes place. In other words provision is made by the described construction for al ways giving substantially the same extent of vibratory movement to the ribbon carrier, although the distance from the fulcrum of the operating lever at which power is applied to said lever may vary.

It will be understood that by my present invention 1 provide means for using the ribbon both lengthwise and crosswise so that the inked surface may be uniformly and thorou hly exhausted. Preferably this feature o my invention is employed with a ribbon having uniform characteristics throughout, althou h of course it may be used if desired in connection with a ribbon having longitudinal fields or stripes of dit' ferent characteristics, such as the ribbon 49 shown in the drawings. Assuming that it is desired to feed the ribbon both lengthwise and crosswise the rod H2 is set in the position illustrated in Figs. 2 and 3, thereby connecting the pinion M with the elliptical gears 1 14 and 117. The operation of the parts when thus connected has already been explained but some additional features may be referred to. It will be apparent that the rack 73 and the ,pinion 94 not only vary the position of the ribbon carrier and its support but that they also serve to maintain said carrier and support in any of the positions to which they may be set r adjusted. this being so by reason of the fiict that the pinion 94 is held from turning except when the elliptical gears are turned: By reason of the reeiprocatory movements communicated to the crank arm :2 from these gears the path followed by the types lengthwise of the ribbon will be serpentine or wavy. The connection between the link 111 and the is such that said link passes from on. side of the center of rotation of said driven gear to the other side. thus reversing the crank arm 10). when said driven gear is being moved at the fastest rate of which it capable. that is. when the teeth nearest to the center of motion on the driven gear are in mesh with the teeth on the driving gear 117 which are farthest from the center of motion. Conscqnently the top and bottom portions of the curved path near the edges of the ribbon will be comparatively abrupt. while the por tions between will be more gradual becau e of the slower rate at which the gear lll is being: driven. Figs. 1 and 14 show the elliptical gears in a relation in which the rate of crosswise feed will be compnraliwly slow, said figures beino assumed to show the pinion 94 connect ed with the elliptical gears.

lomparing these two figures, it will be seen that Fig. 1 shows the ribbon carrier in norand position. the ribbon being maintained aoparatotl from the Front. face of the platen principally lar the llt'llUll of the spring 133. \Yhvn a printing hay is actuatod the stud 1 acting on thr h'rrr arm 125 is adapted to otlort a hodily lJiHYtIUGHt thrroof, ('Elllh'lllg' tho arim lLf to Swing on their pivotal ('ontrra.

Those will ho maintained in tla-ir m-w normal positions by reason of the ongagvim-nt of the (latent 105) with the notch MT. From an inspvction of Fig. 1 it will he UlLfllYBlll that the printing field of lllt' i-ihhou has hifvn lowered so that when lhv typo liars aro'artuatod the upper or red hold 11 id llnrilihon will he prcsonted to the typos whirh will follow a straight path lrngthwise of Said tivld a.

Ihu-ing this l woring moromont whirh. ol' i-ourso, i brought about by the notion of tilt pini n 9i on .liii' IHt'h' 73, a. hort pin 1% l\l lilllHL' latvrally outward from the lever arm 124 will be brought into engagement with the inclined upper edge 139 of an angled plate 140 which is secured by a screw M1 to the rear face of the lefthand upright arm 76 of the guide member. The inclined edge 139 acts on the pin 138 as a cam and forces the bell crank ope at ing lever and the ribbon carrier rearward. overcoming the spring 133 and bringing the vibrator into contact with the pad or step 135 as shown in Fig. 17. The vertical arm 12b of the operating le er will at the same time be moved rearward out of the path of the actuating stud 132. in Fig. 17 one of the type bars is shown by dotted lines in operative position and it will be understood that the printing portion of the ribbon has not only been. lower d out. of the path of the types but that lllllll'flllU- ously the combined action of the pin 138 and cam edge 139 has moved the carrier or vibrator and the printing portion of the ribbon rearward so that they are out of the path of the bodies of the type bars and will not impede or obstruct their proper opera tion. By thin construction the printing portion of the ribbon is movable in two directions at a single ope ation. haid couslruction adapts the invention for use in minieograph work or other styles of work wherein it is desirable to have the types Contact direotly with the work sheet; nor will any unnecessary work be drue in operating the vibrating mechanism since the lever arm 12;) will not. be engaged by the stud 132.

In order again to make use of either the upper field u or lower field I) of the ribbon. it is only necessary to reverse the turning ot the linger button 87 as. above described; and when it is again desired to bring the automatic crosswise feeding devices into play the rod 82 may be shifted longitudinally outward or toward the right until the pinion S -i is again operatively connected with the crank arm 102.

Various changes may be made without departing from the spirit and scope of my inv ntion.
